'o all whom 'it may concern.' y

Be it known that l. DANIEL BisY, a, citizen of the Vnited States, residing at. San Diego. in the@I countyv of San Diego and State of California. have invented a new and useful Terminal or Connector for Electrical Conductors, of which `the following is a specification. t

The present invention appertains to terminals ror connectors for electrical conductors, and aims to provide a novel and improved device of that'character.

lt is the object of the invent-ion to provide a unique, yet simple and inexpensive terniinal or connector for the end of an elec trical conductor which enablessaid conductor to be readily and egectively engaged to a binding post or other element.

The invention elnbodies a terminal or connector of novel construction for receiving and holding the end of the conductor in a thoroughly practical and efiicient manner, whereby the conductor may be readily electrically connected to a binding post or other element.

lith the foregoing and other objects in view `which will appear as the description proceeds, the invention resides in the combination and arrangen'ient ofparts and in the details of construction hereinafter described and claimed, it being understood that -changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the, accompanying drawing, wherein:--

Figure l is a plan viewof the device as applied to the conductor. Fig. 2 is an enlarged sectional view taken on the line 2-2 of Fig. l. Fig. l is a view illustratinr in section, the terminal or connector before the parts are secured together, and illustrating the punch or die in elevation, which is employed l'or securing the parts` together. Fig. l is a reduced sectional View illustrating a modified vtorm with the parts assembled but not `fastened together, and Fig. 5.is a similar view with the parts secured together.

'lbe improved terminal or connector comprises two parts or sections, each of which is pressed or stamped from suitable sheet metal or other stock. (')ne part is in the form of an annular channel member l of arcuate cross section, and having the outer.

curved or curled flange or rim Q. and the inner curved or curled flange or neck 2%. The flange 2 is-relatively low, while the flange or neck 3 is relatively long.y to project beyond the plane in which the edge of the flange Q lies. lrior to the assemblage of the parts. the nec; 3 is cylindrical, as illustrated in F ig. 3.

The other part of the device is-in the form of an annular channel member at of arcuate cross .section and having curled or curved flanges of about equal widths. The external diameter of the member or ring t or the, diameter of the outer tlallge of said member is slightly smaller than the diameter of the flangel Q, whereby the member Lt may fit snugly within the flange 2. and the internal diameter of the diameter Je is slightly larger' than the diameter of the neck or shank 3 to allow the member t to be slipped onto the said neck.

The flange 2 is provided at one Side with an opening or notch 5, and when the parts are assembled. the free end of the neck 3 iS expanded or liared. as at t3, to overlap the member Jr and to hold the two parts orgmcmbers ot' the device assembled.

The conductor or wire 7 passes through the opening 5 and is wound around the neck 5, within the annular chamber between the members l and 4, as at In assembling the device, the end of the conductor is wound or wrapped around the neck 3, as at 8, and the conductor`7 is then disposed within the opening 5. The member t is then slipped upon the neck or shank 3 and is pressed partially within the member l, and the two members are then riveted or secured together, by means of a punch or die t) having a nose 10 adapted to enter the neck 2 and expand the free end thereof, as clearly seen in Fig. 2. rIhe part or member 4 is thus securely held against or within the nembcr l, and this provides an eye or ring upon the end of the conductor for readily and effectively engaging a binding post or other terminal element with which the conductor 7 is to be electrically connected.

The present device is extremely simple and inexpensi ve in construction, and can be assembled with the conductor in a Simple and practical manner. No solder or similar In the modified form, the member 1 is fiat, and has the cylindrical neck or tubular shank 3, and the annular member 4 is channel shaped and is adapted to fit upon the neck 3', whereby the neck 3 can be eX .panded as illustrated in. Fig. 5, to fasten the overlapping and surrounding the outer edge portion of the second mentioned member, the end of said neck being expanded fto snugly overlap the central portion of the second mentioned member, the inner edge of the second mentioned member terminating short of the plane of tbe outeredge of said member, the outer portion of the irst mene tioned member having a notch, and a conductor extending through said notch adjacent the outer edge of the second mentioned member and Wrapped around said neck.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two Witnesses.
